Definitions

  • the invention relates to a cyclone air classifier for separating granular separating material suspended in a conveyor gas, comprising a first, cylindrical hollow body with a tangential to spiral inlet for the conveying gas carrying the material to be separated, one below the first, cylindrical Hollow body located, second, conical hollow body, which is directly connected to the first, cylindrical hollow body, the verjüng te tip of the second, conical hollow body pointing downwards, at least one through the conical wall of the second, conical hollow body pushing immersion tube, which is inside the second, conical hollow body protrudes upwards and the sen opening is arranged in the volume of the first, cylindrical hollow body, wherein the downwardly facing, tapered tip of the second, conical hollow body is connected to an outlet for fine material.
  • Air separators of this type are known cyclone separators in which the material suspended in a gas flow is forced into a vortex in a cone. In the vortex, the granular material separates from the carrier gas due to the centrifugal force.
  • a classifier In classifying it is possible to subdivide the material to be separated into different grain fractions.
  • a classifier there is usually a gas flow inlet, at least one outlet for the carrier gas and at least two outlets for the different grain fractions.
  • a so-called immersion pipe is immersed centrally in the forced vortex, and the carrier gas can flow out through the immersion pipe with ease due to its low density.
  • the denser, granular material collects in the cone tip, where it falls out of an outlet.
  • the immersion tube dips into the center of the vortex from above.
  • the aim is always to achieve the greatest possible separation effect with the lowest possible pressure loss, and thus the lowest possible compressor output.
  • the amount of pressure loss correlates with the separation efficiency.
  • One way to reduce the pressure loss is to dimension the diameter of the immersion tube as large as possible. However, if the diameter of the immersion tube is too large in relation to the cone of the cyclone, the vortex continues in the immersion tube and granular material becomes with it the carrier gas is discharged from the cyclone separator together via the dip tube.
  • the object of the invention is therefore to provide a device for separating granular material to be separated suspended in a conveying gas which increases the classifier efficiently compared to existing solutions.
  • the efficiency is measured by the ratio of the separation performance in% by mass of the granular material that is sifted out in relation to the pressure loss over the separation device. Since the pressure loss increases with increasing flow velocity, but the separation performance also increases, such a separation device usually has a characteristic curve in which the visual efficiency is plotted against the gas flow.
  • the object of the invention is achieved in that a rotating rod basket is arranged in the first, cylindri's hollow body, which is enclosed by a static and circular conveyor trough for coarse material resting on the lower outer circumference, but not touching, the conveyor trough for coarse material with a Output from the first, cylindrical hollow body is connected, and the volume enclosed by the rod basket with the second, conical Hollow body is in flow connection.
  • a rod basket sifter is connected to a cyclone sifter.
  • the rod cage drive which is usually overhead, would collide with the immersed pipe immersed from above.
  • This type of construction enables the immersion tube to have a larger diameter than is the case with generic cyclone separators. This reduces the pressure difference for a given gas flow and thus also the classifier efficiency.
  • the inner volume of the rod cage sifter is directly connected to the cyclone part arranged under the rod cage.
  • the rotating rod basket forces a cyclone that is reinforced in the cone of the cyclone separator.
  • the cyclone receives a push from the rod basket, it is possible, please include to provide the immersion tube with a larger diameter.
  • a circular conveyor trough is arranged below the rod cage, as in a rod cage sifter, into which coarse material falls that could not make its way through the rods of the rotating rod cage. This fraction can be taken as a coarse fraction from the integrated sifter, in which the coarse material trickles out through an outlet.
  • the carrier gas rotates approximately at the speed of the rod cage. Typical speeds of bar cages are 60 m / s circumferential speed with a bar cage diameter of 1 m to 2 m, this corresponds to about 600 to 1,200 rpm.
  • the conveying gas flows into the cyclone part of the integrated sifter, where it has received a pre-acceleration that would otherwise only be achieved by a high flow rate. can be achieved through a narrow supply pipe that blows tangentially into the upper part of the cyclone.
  • the vortex pre-accelerated by the rod cage generates a gas flow that is largely free of particles within the vortex. This particle-free part of the vortex can be diverted through a dip tube reaching up from below.
  • the fine fraction of the granular material accumulates in the peripheral eddy current and leaves the cyclone part of the integrated classifier via the cone.
  • the first, cylindrical hollow body extends below the rod cage and below the rod cage has a height which corresponds to between 50% and 150% of the height of the second, conical hollow body.
  • the height ratio of the conical and the cylindrical part of the integrated classifier affects the efficiency of the separation performance. If the cylindrical part is too high, the vortex in the cyclone can taper into a tube-like vortex like a tornado and thus allow the carrier gas as well as the fine fraction to flow through the immersion tube. If the cylindrical part is too flat, it can happen that the pre-accelerated vortex is forced into the immersion tube and thus the safety efficiency drops.
  • the aim of the optimized embodiment is to widen the pre-accelerated vortex so that a dip tube with the largest possible diameter can hit inside the central vortex.
  • the diameter ratio of immersion tube and cone width has proven to be an important optimization parameter for further optimization.
  • the diameter of the immersion tube corresponds to between 20% and 60%, preferably between 30% and 50% of the inner diameter of the first, cylindrical hollow body.
  • an approximately conical body is arranged above the opening of the immersion tube, the tapered tip of which points upwards, with spiral-shaped guide plates being present on the outer surface of the approximately conical body.
  • the conical body has the function of a round pointed roof, which is arranged like a tower roof above the top of a tower. There is a generous annular gap between the top of the tower and the roof ridge through which the delivery gas can flow into the immersion tube.
  • the roughly conical body with the spiral-shaped baffles supports the expansion of the vortex created by the rod cage, which increases the separation efficiency of the integrated sifter.
  • the approximately conical body is held, for example, by spokes within the first, cylindrical body, wherein the spokes are connected to the wall of the first, cylindrical hollow body, and wherein the height position of the approximately conical body above half of the immersion tube is adjustable, in which the position of the spokes in the wall (W z ) of the first, cylindrical hollow body is height adjustable through elongated holes is. Due to the height variation, the location of the approximately conical body can be optimized depending on the selected flow rate of the carrier gas, so that a maximum expansion of the vortex occurs.
  • the approximately conical body can be arranged statically or it can rotate with the rod cage.
  • the rotating body in the vortex which is reinforced with baffles, helps the vortex forced by the rod cage to generate even more rotational energy, so that the rotational speed of the vortex is not reduced too much when it is expanded.
  • the vortex can also be expanded with a static, inverse impeller.
  • a static inverse impeller consists of guide plates arranged in a ring in the form of a spiral part. There is no baffle in the center of the inverse impeller. The external vortex flow forced by the outer baffles helps the central vortex to expand.
